We visited Mike from The Firing Line, just outside Tulsa, Oklahoma in Oct

He showed us an Operational Briefcase; a “Russian KGB” Briefcase for an AK-47SU (Krink; Short AK-47)
The Operational Briefcase allows the operator to carry the AK securely in any situation without looking like a gun.
When needed the operator instantly has access to the firearm in a shooting condition

Quick look at an Arsenal SLR-107CR (AK47) with the barrel cut down from 16″‘ to 12.5″ (after receiving the ATF paperwork) with a few custom parts. The Aimpoint T1 red dot optic on the UltiMAK railed handguards is easy to acquire and offers a quick sight picture
